An opposed-piston engine is a piston engine in which each cylinder has a piston at both ends, and no cylinder head. Petrol and diesel opposed-piston engines have been used mostly in large-scale applications such as ships, military tanks, and factories. Current manufacturers of opposed-piston engines include Cummins, Achates Power and Fairbanks-Morse Defense (FMDefense).
The EMD 645 is a family of diesel engines that was designed and manufactured by the Electro-Motive Division of General Motors.

The Santa Fe Railroad tugboats were used by the Atchison, Topeka and Santa Fe Railway to barge rail cars across the San Francisco Bay for much of the 20th century, as there is no direct rail link to the San Francisco peninsula. In the post World War II period, a fleet of three tugs moved the barges: the Paul P. Hastings, the Edward J. Engel, and the John R. Hayden. After cross-bay float service had ended and the tugs had been sold, the Hastings sank off Point Arena, California in 1992, in water too deep to raise. The Engel sank off Alameda, California in 2007 and was raised and scrapped in the winter of 2013-14. The Hayden remains afloat and in service in Oregon.

This article covers the History of Sulzer diesel engines from 1898 to 1997. Sulzer Brothers foundry was established in Winterthur, Switzerland, in 1834 by Johann Jakob Sulzer-Neuffert and his two sons, Johann Jakob and Salomon. Products included cast iron, firefighting pumps and textile machinery. Rudolf Diesel was educated in Augsburg and Munich and his works training was with Sulzer, and his later co-operation with Sulzer led to the construction of the first Sulzer diesel engine in 1898. In 2015, the Sulzer company lives on but it no longer manufactures diesel engines, having sold the diesel engine business to Wärtsilä in 1997.
'Brompton Caribou' is 28 feet 6 inches long, 7 feet 6 inches wide and has a depth of 2 feet 9 inches boat commonly known as a "Gator Tug", or "Winch boat" made by the Russel-Hipwell Engines Company in 1955 and is hull number 1058.

This boat also originally had a Russel-Hipweel winch, model W-434 that was driven by a PTO on the front of the engine but it has since been removed. The standard models have a simple rectangle cabin with a large sliding windows on both the port and starboard sides, a smaller sliding window and a door that opens to the inside on the front, and a little sliding door on the back of the cabin. They usually have the exhaust pipe going out through the side of the hull approximately a foot below the bulwarks on an angle facing aft, but many have had the pipe removed and installed going up through the roof of the cabin.
The Cleveland Diesel Engine Division of General Motors (GM) was a leading research, design and production facility of diesel engines from the 1930s to the 1960s that was based in Cleveland, Ohio. The Cleveland Diesel Engine Division designed several 2 stroke diesel engines for submarines, tugboats, destroyer escorts, Patapsco-class gasoline tankers and other marine applications. Emergency generator sets were also built around the Cleveland Diesel and were installed in many US warships. The division was created in 1938 from the GM-owned Winton Engine Corporation and was folded into the GM Electro-Motive Division in 1962. The engines continue in use today on older tugs.

The Type L6 ship is a United States Maritime Administration (MARAD) designation for World War II as a Great Lakes dry break bulk cargo ship. The L-Type Great Lakes Dry Bulk Cargo Ships were built in 1943 to carry much-needed iron ore from the upper Great Lakes to the steel and iron production facilities on Lakes Erie and Ontario in support of the war effort. The ships have a 15,675 tonne deadweight tonnage. The L6 ships were built by two companies: American Ship Building Company, in the case of the type L6-S-A1 models, of which 6 were built; and Great Lakes Engineering Works, Ashtabula, Ohio/ Great Lakes Engineering Works, River Rouge, Ohio, in the case of the type L6-S-B1, which produced 10 ships. Steel supply needed for World War was great. To supply iron ore from Lake Superior to steel foundries, the United States Commission had a series of L6 Lakers ship built. The Maritime Commission ordered ten Great Lakes Bulk Carriers of the L6-S-B1 type. The L6-S-B1 was design with a 3-cylinder triple expansion steam engines. The L6-S-A1 used a lentz 4-cylinder compound engine. All L6 ships were coal burning and delivered between May and November 1943. L6-S-B1 was built for the US Maritime Commission under USMC contract MCc-1834 in 1943 at the River Rouge yard. Each L6 ship cost $2.265 million. The first L6-S-B1 was the SS Adirondack/Richard J. Reiss, hull 290, keel was laid on March 9, 1942 and launched on September 19, 1942. The ships are often called the Class Lake Bulk Freighter now.

Type V ships were used to move ships and barges. Type V tugboats were made of either steel or wood hulls. There were four types of tugboats ordered for World War II. The largest type V design was the sea worthy 186-foot (57 m) long steel hull, V4-M-A1. The V4-M-A1 design was used by a number of manufacturers; a total of 49 were built. A smaller steel hull tugboat was the 94-foot (29 m) V2-ME-A1; 26 were built. The largest wooden hull was the 148-foot (45 m) V3-S-AH2, of which 14 were built. The smaller wooden hull was the 58-foot (18 m) V2-M-AL1, which 35 were built. Most V2-M-AL1 tugboats were sent to the United Kingdom for the war efforts under the lend-lease act. The Type V tugs served across the globe during World War II including: Pacific War, European theatre, and in the United States. SS Farallon, and other Type V tugs, were used to help built Normandy ports, including Mulberry harbour, on D-Day, 6 June 1944, and made nine round trips to Normandy to deliver Phoenix breakwaters.
